Metal complex imidazole fungicides, and methods of controlling fungi with them

Abstract

New fungicidal compounds, and compositions of them and their uses and manufacture are described. The compounds are fungicidal complexes of a metal salt with certain, N,N-disubstituted carbamoyl imidazoles.

We claim: 
     
       1. A solid fungicidal compound of the formula ##STR7## in which M is copper or manganese, n is 2 or 4, and A is chloride. 
     
     
       2. A fungicidal compound according to claim 1 wherein M is copper. 
     
     
       3. A fungicidal compound according to claim 1 wherein M is manganese. 
     
     
       4. A solid fungicidal composition comprising a fungicidally effective amount of a complex compound having the formula: ##STR8## in which M is copper or manganese, n is 2 or 4, and A is chloride; and a fungicidally acceptable carrier. 
     
     
       5. A fungicidal composition according to claim 4 wherein M is copper. 
     
     
       6. A fungicidal composition according to claim 4 wherein M is manganese. 
     
     
       7. A fungicidal composition according to claim 4 wherein the carrier is particulate solids. 
     
     
       8. A fungicidal composition according to claim 1 wherein the composition is in the form of dispersible powders, dusts, and seed dressings. 
     
     
       9. A method for controlling a phytopathogenic fungus which comprises applying to seeds, plants and their habitat the compound according to claim 1. 
     
     
       10. A method according to claim 9 for controlling a fungal disease on a cereal crop which comprises applying the compound to the crop. 
     
     
       11. A method according to claim 9 comprising applying the compound to a broad leaf crop selected from fruit trees, vines, legumes and cucurbits.
